Abstract The electrochemical CO 2 reduction reaction (CO RR) to generate chemical fuels such as formate presents a promising route carbon‐neutral future. However, its practical application is hindered by the competing production and hydrogen evolution (HER), well lack of pH‐universal catalysts. Here, Te‐modified Bi nanorods (Te−Bi NRs) were synthesized through in situ reconstruction Te 4 O 11 NRs under RR condition. Our study illustrates that complex process during could be decoupled into three distinct steps, i.e., destruction , formation Te/Bi phases, dissolution Te. thus‐obtained Te−Bi exhibit remarkably high performance towards production, showing activity, selectivity, stability across all pH conditions (acidic, neutral, alkaline). In flow cell reactor alkaline, or acidic conditions, catalysts achieved HCOOH Faradaic efficiencies up 94.3 %, 96.4 91.0 respectively, at current density 300 mA cm −2 . Density functional theory calculations, along with operando spectral measurements, reveal manipulates sites an electron‐deficient state, enhancing adsorption strength *OCHO intermediate, significantly suppressing HER production. This highlights substantial influence catalyst operational offers insights designing highly active stable electrocatalysts RR.

Developing efficient and robust free-standing electrocatalysts for overall water splitting is a promising but challenging task. Herein, the N-incorporated Ni nanosheets non-fully encapsulated by N-doped carbon (NC) layer are fabricated (N─Ni©NC). The introduction of N not only regulates size in N─Ni©NC also promotes electrochemical activity metal Ni. Experimental theoretical results reveal that strong bonding lattice activates inert promoting charge transfer between N. In addition, upward shift d-band center induced enhances adsorption intermediates, thereby making as new OER active site together with C. This strategy generating C dual sites introducing greatly accelerates oxygen evolution reaction (OER) kinetics, resulting excellent electrocatalytic performance N─Ni©NC. At current density 10 mA cm

Abstract The mild electrosynthesis of urea presents a promising approach to replace the energy‐intensive conventional manufacturing processes, and identifying highly active selective electrocatalysts is paramount importance. Herein, synthesis oxygen‐vacancy‐rich CeO 2 ‐CuO heterostructure nanowires on copper foam (CeO ‐CuO/CF) are reported. CuO‐CeO notably enhances electron transfer quickens reaction dynamics, increased oxygen vacancies greatly promote C‐N coupling nitrate CO urea. As such, ‐CuO/CF achieves remarkable faraday efficiency 31.96% yield 720.9 µg cm −2 h −1 , along with outstanding stability. This research offers electrocatalyst for sustainable on‐site production
